Can't seem to return a nested array within an object fetched with the fetch API. I can return the whole object, but not the properties inside of it

Question

I'm trying to render some data that I'm fetching from the Open Trivia DB. But when I try to map an array (which is the value of am object property), I get undefined on the console.

For now, I want to console.log the array within the object property when the state changes. Later I want to map the results Array to properly render some of the data within the array of objects.

Here's my code:

export default function App(){
  const [quizScreen, setQuizScreen] = useState(false)

  const questions = (
    fetch('https://opentdb.com/api.php?amount=5&category=26&difficulty=medium')
    .then(res => res.json())
    .then(data =>   data)
  )

const startQuiz = () => {
 
  setQuizScreen(prevScreen => !prevScreen)
  console.log(questions.results) //works if I log questions, but not questions.results


}

This is the data:

    "results":[
       {
          "category":"Celebrities",
          "type":"multiple",
